Raw vector
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2021-38406 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Deltaww Dopsoft. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 0.5% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Delta Electronic DOPSoft 2 versions 2.00.07 and prior contain a vulnerability in which the software lacks proper validation of user-supplied data when parsing specific project files. This produces multiple out-of-bounds write instances tracked under CWE-787.
An unauthenticated local attacker can supply a crafted project file that, once opened by a user, allows arbitrary code execution in the context of the current process. The attack vector requires user interaction but no privileges and yields high impact to confidentiality, integrity, and availability.
CISA has issued ICS advisory icsa-21-252-02 on the issue and lists the vulnerability in its known exploited vulnerabilities catalog.

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.
Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.
Secure-development practices (static analysis, bounds checking, code review) are the primary means of preventing out-of-bounds writes.
